I have a server running Windows Server 2008 R2, has installed Symantec Endpoint Protection Manager 11 MR6, then installed Symantec Installation Manager, and when I try to install SMP 7.1, when the SIM is checking the prerequisites show the following error, which is unable to correct.

today with the release of SMP 7.1 SP 1, SIM run again, but it generates the same error.
Anyone can tell me what I have to do to get on the same server: Symantec Endpoint Protection Manager and SMP 7.1 SP1...
